In the spring of 1941, the greater portion of the responsibility for 

 the work in connection with fish screens and fish ladders was placed in 

 other bureaus, and the obligations and responsibilities of the Chief of the 

 Bureau of Engineering were not definitely defined and hence no further

 matters. The problem of fish protection is probably more acute in 

 this State than in some other States due to limited rainfall in certain 

 areas and the numerous and large diversions of water made for agri- 

 cultural, industrial, domestic and poAver purposes.

A number of agencies diverting water, and others, profess to believe 

 that the problem has no solution, and appear to be of the belief that 

 some one fish screen, yet to be found, is necessary before the great loss 

 of fish through these unprotected water diversions can be stopped. 

 The fact that this commission has had installed a number of successful
